The effect of visual and auditory channel interaction on cognitive performance in online education

Abstract: With the arrival of the multimedia era, online education has become one of the main teaching modes. At the same time, the presentation of learning materials has become more diversified, and the interaction mode has gradually developed in the direction of multimodality. According to multichannel cognitive theory and multimedia cognitive theory, human can process information from different channels at the same time, but due to limited cognitive resources, inappropriate content presentation and interaction methods can cause extra load, which will affect learning efficiency. In this paper, we design an experiment to investigate the effects of the visual and auditory channels, as well as the audio-visual channel on people's learning efficiency by presenting and delivering learning information in different ways. The result shows that learning through audio-visual channel is the most efficient interaction method, and learning through a single auditory channel is the least efficient method.
